APPARATUS FOR GARBURETING AIR AND GAS.

SPECIFICATION forming part of Letters Patent No. 312,186, dated February10, 1885.

Applicniitn filed May .21, 1884. (X0 model) To all 2071,0727, it mayconcern:

Be it known that I, JONATHAN S. BUTLER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Apparatus forCarbureting Air and Gas, of which the following is a specification.

The object of this invention is to provide novel, simple, and ciiicientmeans for carbureting atmospheric air and coal-gas by passing themthrough gasoline vapor or hydrocarbon fluid; to provide novel means inthe carburetor for taking up and filtering the liquid gasoline or otherhydrocarbon, and checking or retarding the flow of the vapor through thesame; to provide novel means for agitating the liquid gasoline or otherhydrocarbon, preventing the heavier portions of the same from settlingto the bottom of the pans or vessels in the carburetor, and renderingthe heavier grades of gasoline available, and to provide novel means forpassing atmospheric air into the carburetor to be mixed with thegasoline or other hydrocarbon. These objects I accomplish in the mannerand by the mechanism illustrated in the accompanying drawings, in whichFigure 1 is a vertical central sectional view of the carburetor; Fig. 2,a detached perspec tive view of one of the carburetor pans or trays;Fig. 3, a perspective view with parts broken away, showing thecarburetor connect ed with the air-supplying devices, and Fig. 4 adetached perspective view of the top wall of the air-holder.

In order to enable those skilled in the art to make and use myinvention, I will now proceed to describe the same in detail, referencebeing made to the accompanying drawings, where the numeral 1 indicatesthe carburetor case or box closed to the external atmosphere, andprovided with a valved outlet-pipe, 2, for carrying off the carburetedgas to a gas-holder. The case or box incloses a series of pans or trays,3. arranged one above the other, and closely fitting the interior of thecase or box, so that gas or air entering through the inletpipe 4 at thebottom of the case can only rise from one pan to the other by passingthrough orifices 5 in horizontal end flanges, 6, of the pans, theflanges alternating, so that the airoritices also alternate.

To the under side of each pan is secured a drooping absorbent, 7, ofloose-textured cloth or other similar material, which is suspended fromthe ends of the pans in such manner that hanger, S, carrying a revolvingagitatingwheel in such manner that the wheel of one pan extends into thepan below, the arrangement being such that the wheels alternate and arerevolved by the ascending currents of air or coal-gas passing throughthe orifices'5 and through orifices 9 in the end walls of the pans,thereby continuously agitating the liquid in the pans and preventing theheavier particles of the gasoline from settling to the bottom of thepans, while such agitators render the heavier grades of gasolineavailable. As the pans are not simply open surfaces, but fit the wallsof the case, it follows that the entering air can only rise through theorifices 5 and 9, and consequently the operation of the agitators isinsured.

\Vhere atmospheric air is used in connection with my improvedcarburetor, I provide an inverted cup-shaped air-holder, 10, capable ofrising and falling within a cistern, 11, parti ally filled with water orother liquid; and the inlet-pipe4 to the carburetor is connected by apipe, 12, with a stand-pipe, 13, rising within the cistern andair-holder, with its upper open end abovethe level of the liquid seal inthe cistern. The air-holder has its top plate, 14, provided with meanswhereby air can be admitted to the holder, and this means preferablyconsists of an orifice, 15, in said top plate, adapted to be opened andclosed by a valve plate, 16, hinged to one edge of the orifice andconnected with one end of a coiled or other spring, 17, the other end ofwhich is connected with a cross-bar, 18, on the top plate. Thiscross-bar carries friction-wheels 19 at its outer ends, which travel onvertical guide-standards 20 in such manner that the rising and fallingmovements of the air-holder are steadied and rendered free and easy. Thespring serves to close the valve after sufiicient air has been admittedto the air-holder.

The air-holder can be raised by weights or other mechanical devicessuchas a Windlassas shown in Fig. 3.

I am aware that heretofore air has been forced through a case containingvessels for holding hydrocarbon fluid, the air in its passage acting torevolve a wheel in a horizontal direction, from which depend fingers toagitate the fluid in the vessels; such, therefore, I disclaim.

Having thus described my invention, what I claim is 1. The combination,with the carburetorcase and air or gas forcing mechanism connectedtherewith, of a pan fitting the interior of the case, and a winged wheeljournaled to revolve in a vertical plane with its wings in the fluidcontained in the pan, substantially as described.

2. The combination, with the carburetorcase having an inlet foratmospheric air or coal-gas, ot' a series of pans fitting the case, oneabove the other, and provided with alternating end orifices, and thealternately'arranged agitating-wheels supported, respectively, in theend portions of the pans, and revolved by the ascending air or gaspassing through the said end orifices, substantially as described.

3. The combination, with the carburetorcase having an inlet foratmospheric air or coal'gas, ot' pans closely fitting the case, oneabove the other, and provided with end orifices, hangers suspended fromthe bottoms of the pans, and agitatingwheels suspended by the hangers inthe pans respectively, and re volved by the ascending currents of air orgas passing through the end orifices, substantially as described.

4. The combination, in a gas-carburetor, of a case having an inlet foratmospheric air or coal-gas, a series of pans fitting the case, oneabove the other, and provided with alternating end orifices, absorbentsdrooping from the under sides of the pans, so that one extends into thepan below it, and revolving agitating-wheel s supported alternately inthe ends of the pans, substantially as described.

5. The combination, with the carburetorcase, the pans therein, theagitating-wheels, and suitable absorbents, of acistern, a rising andfalling air-holder therein provided with means to admit air therein, andpipes connecting the carburetor-case with the air-holder, forintroducing air into the carburetorcase and revolving theagitating-wheels therein, substantially as described.

6. The combination, with the carburetorcase, the pans therein, theagitating-wheels, and suitable absorbents, of the cistern, theguide-standards, the rising and falling airholder having an orificeinits top and a crossbar carrying rollers, a valt e for opening andclosing said orifice, and a spring connected with the valve for throwingit closed, substantially as described.
